Abstract

A nail glue composition contains Beta-methoxyethyl cyanoacrylate, octyl cyanoacrylate, and polymethyl methacrylate. The nail glue composition is substantially odorless and has increased softness.

Claims

exact text as granted — not AI-modified
I claim: 
     
       1. A nail glue composition comprising: Beta-methoxyethyl cyanoacrylate, 2-octyl cyanoacrylate, polymethyl methacrylate, and a calcium gluconate additive, wherein the nail glue composition is free of ethyl cyanoacrylate. 
     
     
       2. The nail glue composition of  claim 1 , wherein the 2-octyl cyanoacrylate is medical grade 2-octyl cyanoacrylate. 
     
     
       3. The nail glue composition of  claim 1 , wherein the Beta-methoxyethyl cyanoacrylate is present in the range of about 60 to about 84 wt % of the nail glue composition. 
     
     
       4. The nail glue composition of  claim 1 , wherein the 2-octyl cyanoacrylate is present in the range of about 2 to about 40 wt % of the nail glue composition. 
     
     
       5. The nail glue composition of  claim 1 , wherein the polymethyl methacrylate is present in the range of about 0.1 to about 10 wt % of the nail glue composition. 
     
     
       6. The nail glue composition of  claim 1 , further comprising a protein additive. 
     
     
       7. The nail glue composition of  claim 6 , wherein the calcium gluconate and protein additives are present in the range of about 0.01 to about 1 wt % of the nail glue composition. 
     
     
       8. The nail glue composition of  claim 7 , further comprising a keratin amino acid in the range of 0.01 to 1 wt % of the nail glue composition. 
     
     
       9. The nail glue composition of  claim 1 , further comprising a vitamin additive selected from a group consisting of Vitamin A, Vitamin E, and a combination thereof. 
     
     
       10. The nail glue composition of  claim 9 , wherein the vitamin and calcium gluconate additives are present in about equal proportions. 
     
     
       11. A nail glue composition comprising: Beta-methoxyethyl cyanoacrylate, 2-octyl cyanoacrylate, polymethyl methacrylate, and a combination of vitamin, calcium gluconate, and protein additives, wherein the nail glue composition is free of ethyl cyanoacrylate. 
     
     
       12. The nail glue composition of  claim 11 , further comprising a keratin amino acid additive. 
     
     
       13. The nail glue composition of  claim 11 , wherein the additives are present in the range of 0.01 to 1 wt % of the nail glue composition. 
     
     
       14. The nail glue composition of  claim 11 , wherein the protein additive is a silk protein. 
     
     
       15. The nail glue composition of  claim 11 , wherein the Beta-methoxyethyl cyanoacrylate is present in the range of about 60 to about 84 wt % of the nail glue composition, the 2-octyl cyanoacrylate is present in the range of about 2 to about 40 wt % of the nail glue composition, and the polymethyl methacrylate is present in the range of about 0.1 to about 10 wt % of the nail glue composition. 
     
     
       16. A nail glue composition comprising: Beta-methoxyethyl cyanoacrylate, 2-octyl cyanoacrylate, and polymethyl methacrylate, with a combination of protein and calcium gluconate additives, wherein the nail glue composition is free of ethyl cyanoacrylate. 
     
     
       17. The nail glue composition of  claim 16 , further comprising a keratin amino acid additive. 
     
     
       18. The nail glue composition of  claim 16 , wherein the additives are present in the range of 0.01 to 1 wt % of the nail glue composition. 
     
     
       19. The nail glue composition of  claim 16 , wherein the protein additive is a silk protein. 
     
     
       20. The nail glue composition of  claim 16 , wherein the Beta-methoxyethyl cyanoacrylate is present in the range of about 60 to about 84 wt % of the nail glue composition, the 2-octyl cyanoacrylate is present in the range of about 2 to about 40 wt % of the nail glue composition, and the polymethyl methacrylate is present in the range of about 0.1 to about 10 wt % of the nail glue composition.
